I have that message on my device under the IN/OUT tab. It's an enttec OPEN DMX.
When I refresh (under setting) the device, it goes to GOOD.
But after a undefined period of time, it goes back again to BAD.
What does it mean and can I fix it ?
Would a enttec PRO USB improve that ?
I experience no flickering during a show, only if I hot plug/unplug the device.
